I thought I might have squeeze some wire into groove in the doser ring, especially near the front to stop the funnel dropping out of the groove and possibly using some epoxy resin to stop it coming loose. I was going to use a brass flap as I did in the case of the Rossi but discovered the mounting screws are too low in relation to the opening so I simply refitted the plastic flap from the doser Pic 4 Pic 2 shows the finished funnel and Pic 3 shows it mounted on the grinder. Used some wet and dry sand paper to try and smooth the inside of the funnel as I did in the case of the Rossi. I then cut the bottom tip of the funnel to enlarge the outlet hole as I did in the case of the Rossi. Next I drilled two mounting holes in the lugs lining up with the mounting holes in the ring. I then cut off the folded top rim of the funnel and then cut further down but leaving two 'lugs' to attach the funnel where the ring is attached to the grinder.

However when I thought about the design of the Compak and how it differed from the Rossi I came to the conclusion the best (and easiest) way to mod the funnel was to retain the upper chromed metal ring of the doser and cut the funnel so the upper edge of the funnel tucks into the deep groove on the bottom edge of this ring see pic 1. The first part of the modding of the funnel is identical to that what I did for the Rossi so I will not repeat it. My third octopus funnel finally arrived after a 2 1/2 month trip from China after being stuck in Singapore because of COVID. I have noticed more recent ones run faster though I have a copy of a Compak note indicating they did make a 240V version that ran at 870 rpm. One thing I have always been curious about my Compak K8 is that it has a sticker underneath claiming it runs at 880 rpm. However just as in the case of the Rossi, I have never been keen on the commercial doser for home use. Just seemed to grind a bit better, is quieter and has larger burrs. I picked up a Compak K8 Silenzio on evilbay about 8 years ago and have always believed it better than my Rossi RR45. This is a follow up post on Octopussying yet another Rossi RR 45 Grinder.
